According to one embodiment, an apparatus includes zone classifier logic to map base chrominance components of pixels of color data to zones within a color space, where each zone is assigned a gain value. Saturation detection logic generates saturation values from the base chrominance components for each pixel of the color data. Saturation transformation logic transforms the saturation values to sigmoidal output values based on a sigmoidal transformation model. Chrominance enhancement logic generates enhanced chrominance components for each pixel of the color data based on the base chrominance components, the saturation values, the sigmoidal output values, and gain values assigned to the zones to which the base chrominance components are mapped."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for color enhancement","description":"Apparatus, methods, and other embodiments associated with image processing operations are disclosed that provide image color enhancement.
